Surely [Sir Garnet concluded] John Bull will not endanger his birth-right, his property, in fact all that man can hold most dear ... simply in order that men and women may cross to and fro between England and France without running the risk of seasickness. Sir Garnet reinforced the arguments against the tunnel in personal testimony before the committee. In this testimony he emphasized, among other things, his conviction that once an enemy got a foothold at Dover, England would find herself utterly unable "short of the direct interposition of God Almighty"—an eventuality that Sir Garnet did not appear to count on very heavily—to raise an army capable of resisting the invaders. And the inevitable result of such a default, Sir Garnet told the committee, would be that England "would then cease to exist as a nation." Sir Garnet's fears for Britain were not shared in a memorandum submitted to the committee by another high Army officer, Lieutenant-General Sir John Adye, the Surveyor-General of the Ordnance. Sir John gave his opinion that "a General in France, having the intention of invading England, would not, in my opinion, count on the tunnel as adding to his resources." He maintained that the argument that the English end of the tunnel might be taken from within could be safely dismissed, as invading troops could be destroyed as they arrived "by means of a small force, with a gun or two, at the mouth of the tunnel." As for the possibility of a hostile force landing on British soil to seize the mouth of the tunnel, he questioned whether "an enemy, having successfully invaded England, [should] turn aside to capture a very doubtful line of communication, when the main object of his efforts was straight before him." General Adye thought that the invaders "would probably feel a much stronger disposition to march straight on London and finish the campaign."
